If anyone had told me year ago that I'd be writing smut about a likely gay robot, I would've laughed sadly because it had already begun (2 yrs already!) Mettaton lemons and one shots for all of the robotfuckers out there! I will take requests if you have any. This includes AUs and threesomes. Enjoy ya filthy sinners!

(to all the people that bother reading these) OK before anyone reads these just remember I have no idea what all the characters are like I don't know much about undertale and well I just looked over some stuff about the characters in these and also I'm going to be writing a lot of episodes because I'm another sad sinner with nothing else to do with my life WARNING A LOT OF LEMONS IN THE EPISODES THEY CAN COME SUDDENLY SO YEA... Aka I have no information about the characters I use in these so don't be mad if some don't make sense I'm trying OK \(¬_¬)/ Things you must keep noted -spelling mistakes - untrue facts about story (characters, places etc.. ) OK well that's all hope you enjoy the little things I'm doing to make this world a вєттєя place. And watch out for the cringe parts (there are so many I cringe at just by reading them over) /(・ × ・)\ (my first ever story soo) oh and I'm to lazy to add picutres

(Y/N) is an artist. An extraordinary one to say the least. She is quickly climbing her way up the ranks. And who knows, one day she may even become famous. But something is preventing her from reaching her goal. It isn't anything about her art style, or her coloring skills, or even what she prefers to draw. No, this girl is half human, half skeleton. Yes, and most humans strongly dislike the monsters. The ones that don't strongly dislike them don't care, and they are the ones that buy (Y/N)'s art. And the monsters themselves, of course. Since she was little, she was hoping so very much to be able to take a trip to the Underground to meet some monsters, especially Mettaton, who was rumored to be the most popular monster in the entire Underground. She has finally saved enough money to buy a car, but... someone beat her to it. A little kid named Frisk has set them all free, and they have been roaming around for two years now. This is where our story begins. (This is UnderTale if you didn't know)

Your best friend is an aspiring celebrity, who happens to hate Mettaton. But you both travel to his show to gain popularity. You loved Mettaton and his work, but you really didn't want to be on stage. But when an unexpected event happens, what will you do when you are face-to-face with the spotlight? (currently working on making this story gender neutral!) And thank you to whoever made the absolutely beautiful picture I used for the cover! All fan-art used in this book is owned by its original creators, not me. Undertale is owned by Toby Fox. SPOILERS COMPLETED (for now) READ! PREVIOUSLY PONYGENIUS13 (I CHANGED MY NAME)

Warning! This story may contain spoilers for the pacifist run of Undertale, so made sure you've finished that first! There IS NSFW/Lemon in this story, but it is only for a brief chapter-and it is not required that you read it. You've been in the underground for a while. You're only a human, but you've decided to stay in the underground instead of leaving everything behind to reach the surface. You're a big fan of the star of the underground, Mettaton-you couldn't explain how you felt about him in any way other than that you were romantically attracted to him...Especially in his newer form... This is the second x Reader fanfic I've done so far and oh man I'm really excited to write this one! To be honest I've been really excited to get to this one which might explain my compulsive updating on the previous one...Oops.
